It will produce Figures 1 and 2 in the Charts in Excel folder. 

To keep the formatting of the charts, do not delete Figures 1 and 2 files as the do-file only modifies the numbers inside excel without touching the formatting. 
If you delete the excel files, the formatting of the charts will disappear and only values will be exported by STATA.
